It was performed on Tuesday during the evening art show for the fourth Summit of Conference on Interaction and Confidence-Building Measures in Asia in Shanghai.

The song, also known as the oriental serenade, was sung by the Shanghai-based East China Normal University choir.

Twenty male students and 28 female students were selected to participate in Tuesday's art show.

They prepared for nine days to deliver a high-level performance.

"I was very tired during rehearsals and also sacrificed a lot of time to rest. But I still feel very honored to have the chance to perform on the same stage with so many top performance groups," said a student surnamed Yuan.

Consisting of about 80 students studying various majors, the university choir is well-known for its high performance standard and has won many international and domestic awards.
